Thanks a lot for your comments. Yeah, UIUC was always a reach for me.
About 15% of my senior class is enrolled in multivar/matrix algebra (the most the school has ever had, they had to create a new session for it). Honestly, I like my BC class though. The teacher is funny and can make the class interesting. Also, I am enjoying the content in general, I can literally see the applications through both physics and stats.
I did technically apply to LAS but it was CS+Math so it doesn’t rely count. It was honestly so perfect because I intend to minor/double major in math regardless of where I go.
As for the Physics, my teacher prepared me well I think. Yeah it was a hard exam but not too bad. I honestly didn’t give much thought to it since a Physics 1 score doesn’t matter. It is algebra-based and therefore not equivalent to a first-semester physics course. I am taking Physics C though so I can hopefully get a 4 or 5 to place out of credit.
